Lilliputian \lil-i-PYOO-shuhn\ , adjective;
1. Extremely small; tiny; diminutive
No need to consult the dictionaries for the etymology of this one! Jonathan Swift wrote about the people of Lilliput who were only 6" tall in Gulliver's Travels (1726). A story this iconic becomes part of our collective knowledge, so words and phrases are easily translated into our day-to-day speech without specifically mentioning its source. See frabjous for a similar type of word from C.S. Lewis.
Speaking of C.S. Lewis, this made me laugh.
